Flat light spreads fish out and holds them shallow through the middle of the day.
In the water now · September
The sport fish active near Yellowknife, Northwest Territories in September — where they hold, how to know one on the line, and the tactic that usually works. Check your licence and the current limits before you go.

Sander vitreus
Olive-gold flanks, a spiny first dorsal, and the big glassy eye that gives it the name and lets it hunt in low light.

Esox lucius
Long torpedo body, duck-like jaws, light bean-shaped spots on a dark green flank.

Nothing here is a guess. Each of these is read from this week's forecast and this location's climate record, and each one is pushing the season one way or the other.
Waxing Crescent · 11%
Waxing, 3 days old. Full moon in 11 days. Fishing outlook: good.
It moves water — in the sea, in a lake's edge, and, by long tradition, in the sap of a plant. Fish feed hardest on the days around new and full.
13 km/h now · 20 peak
A working breeze: it ripples the surface, drifts a boat at a fishable speed, and stacks bait on the windward shore. Anglers call it a walleye chop.
It pollinates corn and grasses, dries soil, breaks stems — and it decides where the bait, and therefore the fish, end up.

The moon
Waxing Crescent
11% lit · waxing · day 3 of 29.5
Planting by the moon: New to first quarter: sow leafy crops and anything harvested for its leaves — lettuce, spinach, brassicas, herbs.
Fishing: good — feeding peaks in the days either side of new and full, and around moonrise and moonset.
Turn of the season
Fall equinox
Sep 22 · 7 days away
About 11 days to the average first frost (Sep 25).
Next moons
6.8 mm / 7 days
6.8 mm across 2 days — short of the ~25 mm a week most beds want. Top up the thirstiest rows.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.
8.4 °C
Cool-season seed only — peas, spinach, radish, fava, and the first lettuce. Beans and corn will sulk.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
12h 59m
Losing about 6 minutes of daylight a day.
The one thing weather can't change. Plants count photoperiod to decide when to bolt, bulb, flower and go dormant.
11 days
Average first fall frost is around Sep 25. Nothing you sow now will finish unless it beats that.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
